3D Surface Topography Measurement for Textiles
topic
Three-dimensional surface measurement systems using structured light projection, laser triangulation, or confocal microscopy quantify the surface topography of textile fabrics by measuring pile height distribution, fibre protrusion profiles, emboss depth, and surface roughness parameters including Ra, Rz, and Rmax that characterise the tactile handle and visual appearance of pile fabrics, nonwovens, and finished textile surfaces at micro-scale resolution.
Role
Provides objective quantification of textile surface texture that correlates with the tactile handle and appearance properties that determine consumer quality perception but cannot be measured by conventional two-dimensional fabric testing, enabling systematic development of surface finishing processes targeting defined 3D texture parameters and quality control of pile height uniformity in velour, carpet, and raised fabric production where surface texture consistency is the primary aesthetic quality parameter.
